The Epworth sleepiness scale is a self-administered eight-item questionnaire that was developed as a tool to measure subjective sleepiness in adults. The validity of the Epworth sleepiness scale has been validated and tested in different populations and ethnic groups. However, it has yet to be validated or tested in an Omani or other Arabic speaking population. Thus, the aim of this study is to test the validity and reproducibility of the Epworth sleepiness scale in an Omani population.
Subjects were recruited from the general population and were asked to participate in the study. The study enrolled 97 Omani volunteers and was conducted between May and October 2008. An Arabic version of the original English questionnaire was used. The study was approved by the Research and Ethics committee of the institution. Lin's concordance correlation coefficient along with Bland-Altman plots were used to test the agreement between the Arabic and English versions of the Epworth sleepiness scale.
The study included a total of 37 males (38%) and 60 females (62%) with age ranging between 18-75 years. Concordance correlation results revealed a substantial concordance (RhoC) of 0.914, but one that does not approach 1 (95% CI: 0.881, 0.947). This results from both lack of perfect correlation (Pearson's r=0.914) and bias (C_b = 1.000). The Bland and Altman's limits-of-agreement measured at 0.000 (95% CI: -2.684, 2.684), indicating insignificant average departure from agreement between the two versions of the Epworth sleepiness scale.
The results indicate agreement between the two versions of ESS (English and the Arabic).
爱泼沃斯思睡量表是一份包含八个条目的自填式问卷,作为测量成年人主观嗜睡程度的工具而开发。爱泼沃斯思睡量表的有效性已在不同人群和种族中得到验证和测试。然而,它尚未在阿曼或其他讲阿拉伯语的人群中进行验证或测试。因此,本研究的目的是测试爱泼沃斯思睡量表在阿曼人群中的有效性和可重复性。
从普通人群中招募受试者并邀请其参与研究。该研究纳入了97名阿曼志愿者,研究于2008年5月至10月进行。使用了原始英文问卷的阿拉伯语版本。该研究获得了该机构研究与伦理委员会的批准。使用林氏一致性相关系数以及布兰德-奥特曼图来测试爱泼沃斯思睡量表阿拉伯语版和英语版之间的一致性。
该研究共纳入37名男性(38%)和60名女性(62%),年龄在18至75岁之间。一致性相关结果显示一致性程度较高(RhoC为0.914),但未接近1(95%可信区间:0.881,0.947)。这是由于缺乏完全相关性(皮尔逊r = 0.914)和偏差(C_b = 1.000)所致。布兰德和奥特曼的一致性界限测量值为0.000(95%可信区间:-2.684,2.684),表明爱泼沃斯思睡量表两个版本之间的平均差异不显著。
结果表明爱泼沃斯思睡量表两个版本(英语版和阿拉伯语版)之间具有一致性。
